1. given/known data My work is about calculating activation energy of bromate/bromide reaction. Besides KBr and KBrO3, phenol and methy red is also used. The Bromine produced react rapidly with phenol, once all the phenol is consumed, the bromine will decolorize the methyl orange indicator. In that way the time for a reaction to reach a certain point can be determined 2. Relevant equations BrO3- (aq) + 5 Br- (aq) + 6 H+ (aq) → 3 Br2 (aq) + 3 H2O (l) My question is, what is the gel-like substances i found at the end of the reaction?
